项目摘要

Millimeter-wave (mmWave) communication is a promising solution to the current global shortage of bandwidth created by the rapidly growing demand for mobile data. While channel modeling and propagation characteristics for mmWave transmissions are fairly well understood, transient channel characteristics including how the hand of a human blocks antennas in a handset requires new, detailed research. Further, the impact and nature of interference in the face of mmWave directional beamforming are yet to be well explored. The key aspects of this proposal dealing with transient channel characterization and interference modeling will directly contribute to the realization of mmWave communications, which is envisioned not only for traditional fixed infrastructure cellular services but also for emerging, more prevalent, new service modes including unlicensed/licensed and mobile usage such as on buses, trains and cars, and peer to peer communications.This proposal advances understanding in several fundamental aspects of mmWave communications. First, the proposal characterizes transient physical effects in mmWave channels such as fading due to human hand, head and body placement when holding phones. This characterization will be carried out with extensive measurements using directional antennas and novel modeling methodology employing finite-state Markov models. These transient channel models will then be integrated into the open-source measurement-based channel simulation platform NYUSIM, which generates realistic mmWave channel impulse responses under a wide range of practical settings. Second, the proposal provides analytical models of the interference distribution in a mmWave cellular system employing beamforming, including explicit probability density functions for the interference power at each receiving antenna element and interference correlation between different antenna elements as well as correlation between interference signals and intended signals. These distributions are parameterized and heavy-tailed in order to capture the large fluctuation in mmWave signals due to strong shadowing and a high probability of NLOS propagation in typical mmWave applications of dense environments. The interference models are verified by comparing with a system simulation using stochastic geometry to model locations of users and base stations and using NUYSIM to generate realistic mmWave channels among all nodes. The proposed research integrates measurement, modeling, theory, and analysis to advance fundamental understanding of mmWave communications, providing a means towards designing and evaluating mmWave communication systems.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

毫米波（MMWAVE）通信是对当前对移动数据需求迅速增长的带宽的全球带宽短缺的有前途解决方案。虽然对MMWave传输的通道建模和传播特性知之甚少，但瞬态通道特征，包括人的手在手机中如何封闭天线的手如何需要新的，详细的研究。此外，面对MMWave定向光束形成的干扰的影响和性质尚待探索。 The key aspects of this proposal dealing with transient channel characterization and interference modeling will directly contribute to the realization of mmWave communications, which is envisioned not only for traditional fixed infrastructure cellular services but also for emerging, more prevalent, new service modes including unlicensed/licensed and mobile usage such as on buses, trains and cars, and peer to peer communications.This proposal advances understanding in several fundamental MMWave通信的各个方面。首先，该提案表征了MMWave通道中的瞬时物理效应，例如握住手机时人的手，头部和身体放置而褪色。该表征将使用有限状态马尔可夫模型的定向天线和新型建模方法进行广泛的测量。然后，这些瞬态通道模型将集成到基于开源的基于基于开源的通道模拟平台Nyusim，该平台在广泛的实际设置下生成现实的MMWave通道脉冲响应。其次，该提案提供了采用波束形成的MMWave细胞系统中干扰分布的分析模型，包括在每个接收天线元件处的干扰功率的明确概率密度函数以及不同天线元件以及干扰信号和预期信号之间的相关性之间的干扰相关性。这些分布是参数化和重尾的，以捕获MMWave信号中的较大波动，这是由于较强的阴影和在典型的密集环境中典型的MMWave应用中NLOS传播的概率。通过与系统模拟使用随机几何形状进行模拟用户和基站的位置，并使用Nuysim在所有节点之间生成现实的MMWAVE通道来验证干扰模型。拟议的研究集成了测量，建模，理论和分析，以提高对MMWave通信的基本理解，为设计和评估MMWave沟通系统提供一种手段。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估来通过评估来支持的，这是值得的。
